Machine safety refers to the measures and practices implemented to protect workers from injuries and accidents caused by machinery during operation, maintenance, or cleaning. It involves identifying potential hazards, implementing safeguards such as guards, interlocks, and emergency stop systems, and ensuring proper training and supervision. Adhering to safety standards (like ISO 12100 or OSHA guidelines) helps prevent mechanical, electrical, and ergonomic risks. Effective machine safety not only safeguards personnel but also enhances productivity and operational reliability.
